It has to cross Tori Spelling's mind that while she and Dean McDermott both cheated on their spouses when they first got together, history would repeat itself?

While having gelato with a friend of hers, Spelling says she hasn't really processed everything that's happened in her marriage to McDermott in the last few months.

In Dec. it was revealed that McDermott, 47, cheated on Spelling, 40, with a 28-year-old woman in Toronto while he was there filming Chopped Canada.

"Because this whole affair has been made so public, I guess I assume that everyone is just like, okay, we know what's going on," Spelling tells her friend Andy.

"So, when I hear my friends day to day say, 'You're not dealing with stuff,' it's just shocking to hear that and it puts it all into perspective."

"How forgiving are you in this situation?" Andy asks the former 90210 star.

"I don't know, we'll find out," she concedes.
